Bendable Material/ Propane - Forno Bravo Forum: The Wood-Fired Oven Community



New Forno Bravo Forum Feature

Forno Bravo Forum Community,

You will notice a new forum at the top of the main page called, "Ask Me Anything". This forum will be used for live one hour "Ask Me Anything" (AMA) sessions hosted by people who are knowledgeable in different areas pertaining to wood fired ovens. How it works:
- Each AMA will have a "sticky" thread where the community can post questions they would like answered during the live session. This will allow everyone to participate even if you can't be online for the live session. These questions will not be answered by the host until the live AMA; if you need an answer quickly, you should post it in the appropriate Forum area for the community to respond.
- Another thread will be posted for the live AMA. Registered users who are logged in during the live session can interact with the host by asking questions and receiving responses.
- The live thread will remain in the AMA forum to view after the session.

To kick off our AMA feature, we have invited author, chef and master bread maker and host of Pizza Quest, Peter Reinhart, to be our first host! Peter will be in the Forum on Monday, February 15th, from 7:00 - 8:00 pm EST. If you are unable to be online during the live session, you can post your questions in the sticky post. Peter will answer those questions during the live session on February 15th. You can view Peter's answers to your questions as well as what happened during the live session in the session thread.

We hope you enjoy this new feature! Please let us know if there is a topic that you'd like to have as an AMA and we'll look for a host!

  • Bendable Material/ Propane

    Can anyone tell me what type of bendable material they had used to make a rounded formation which sits at the mouth of the oven for their hearth/top slab?

    I also seen a video where someone constructed their oven and added a propane kit to it. I assume would work well as a starter. What do I need to buy or look for to accomplish this.

    Thank You

    Re: Bendable Material/ Propane

    I just poured a hearth yesterday and also put an arc in the front. My arc is about 5" from front to back. I'll post pictures to my thread tomorrow. I used a cement expansion board (like a heavy, pressed cardboard that is somewhat bendable) and placed a sheet of 6mm plastic between it to prevent the concrete from adhering to it. I put that on top of cement board and then cut it down to be the same height as the 2x6 form.

    This project is my first experience pouring concrete, so there might be a more professional way, but what I've described appears to have worked pretty well for me. Good luck! Post some pics along the way.

        Re: Bendable Material/ Propane

        While I have not experimented with the use of gas/propane, the threads that I have read strongly suggest to be very careful if you decide to use one of these fuel sources. If your flame goes out and gas builds up within the dome, you could put in place all the elements for an unexpected and unwanted fire works display.

            Anything that bends makes a fine curved form. Quarter inch luan makes a good curve, with some backup so it doesn't bow out with the weight of the concrete.

            It the official policy of Forno Bravo that gas burners in home ovens aren't safe. Please take all such discussions off line. Thanks.
